IMPROVEMENT IN MAGAZlNE-STOVES.

Specification forming part of Letters Patent No. 163,442, dated May 18,1875; application filed March 6, 1875.

To all whom it may concern:

Be it known that 1, WILLIAM W. BALDWIN, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Stoves; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to i which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in stoves designed for heatingapartments, and is so fully described in the following description andclaims that no preliminary recital is needed.

In the drawings, Figure 1 is a longitudinal vertical section of a stoveembodying my improvements. Fig. 2 is a detached view, showing, in plansection, the opening 0 at the base of the exit-flue.

A is the fire-pot, B, the combustion-chamber; G, the exit-flue, leadingto the smokeflue. D is the smoke-flue. It may or may not be providedwith divisions D D, whereby the products of combustion may be made todescend, circulate about the ash-pit, and ascend into the smoke-flue D,which, however,

forms no part of my invention. E is the fuel-' reservoir. It is providedwith perforations or slots e. F is an air-space left between theperforated wall of the reservoir and the outer wall G of thedrum-section of the stove. H is a register, for admitting external air.I is a flue, leading from the air-chamber F into the smoke-flue D. t isa damper. f is a diminished orifice, through which the gases that maycollect in the chamber F are discharged into the combustion-chamber B.

The operation of the device is as follows: Fuel contained in thefuel-reservoir E will, when the stove is Well heated, emit gases, whichsaid gases will escape into the room and become obnoxious, unless meansare provided for their escape or consumption. This is effected bypermitting them to escape into the chamber F, thence carried by thedraft downward through the diminished orifices f,

where they are consumed in the combustionchamber; and to assist thisconsumption, and at the same time furnish more oxygen to the flame inthe combustion-chamber, a register, H, is provided, whereby external aircan be admitted. When it is desired to diminish the heat of the stove,and for that purpose quell the combustion in the combustion-chamber B,the damper -i in the flue I is opened, and the gases in the chamber Fpermitted to escape directly into the smoke-flue D, instead ofpermitting them to descend into the combustionchamber B.

It will be noticed that the outer wall G of the drum-section of thestove forms the outer wall of the air-chamber F, and this outer wall ordrum is dropped down into the combustion-chamber, so as, by itscontinuation, to diminish the air-space F, and form a contractedopening, f, at the bottom.

I am not aware that a stove provided with such a perforated reservoirand air-space, F, has ever before been provided with a flue, I, and withor without a damper, i; and I am not aware that a stove of thisdescription has ever before been made with a fuel-reservoir, and asmoke-flue, D, leading therefrom, the opening 0 into the said flueextending below the base of the said fuel-reservoir, whereby thesmoke-flue within the limits of the stove is made to form a portion ofthe combustionchamber.

What I claim is- 1.' The combination, with the reservoir E and openingf, of the opening 0, made to extend below the lower end of the wall G,substantially as and for the purpose described.

2. The combination, with the perforated reservoir E, the perforations ofwhich communicate directly with the air-space F, and the airspace F, ofthe flue I and damper i, substantially as and for the purpose described.

3. The combination, with the perforated reservoir E, the perforations ofwhich connect directly with the air-space F, of air-space F, flue I, andair-register H, substantially as and for the purpose described.

4. The combination, with the combustion chamber B, perforated reservoirE, the perforations of which communicate directly with the air-space F,and air-space F, of the exitflue O and flue I, substantially as and forthe purpose described.

5. The combination, with the combustionchamber B, air-space F, and fluesO and I, of

the air-register H, by which means the draft has direct transit throughthe reservoir E without passing down by an indirect course,substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM W. BALDWIN.
